HELP: iso pentagon/hexagon?

Recommended Posts

aallaux

Hello. I'm currently a freshman an engineering student at UVM.

 

I'm in a basic autocad class now, and am only using orthographic and isometric views (don't know 3-d autocad yet). For a final project, I am constructing a treehouse using either a pentagon or hexagon shape. What neither I nor my professor can figure out is how one would build this using the iso setting.

Using the ellipse to construct this seems to be the right way, but I can still not determine what the angles would be. Also, because it is to be done in isometric view, all the sides of either the polygon or pentagon would have to be true lengths (equal lengths).

 

Any and all help is welcome. Thanks!

I think it would be easier to learn 3D to model this.

The simple method.

You draw the pentagon in ortho view, surround that with a rectangle. Draw an iso square the same size. Locate the endpoints of the pentagon by measuring where the line intersect the rectangle, transfer the dims to the iso, connect the dots.

Your still using a slide rule in a calculator world. It seems to me your time could be better spent in your eng class dealing with real world situations and modern CAD methods... Just a thought...
